HAND EMBROIDERINGMAGHINE Specification of Letters Patent.

Patented Uc't. 28,1 9 t3.

Application filed February 18, 1911. Serial No. 609,438.

To all whom it may concern:

' conveniences found in the usual i'orm of em# broidering machine now in use.

l attain these objects by the mechanism illustrated in the accompanying drawing, in which* Figure l is a front elevation, Fig. 2 a side elevation of a machine embodying my invention, Fig. 3 a cross section on the'line .3v-3, Fig. f2, Fig. 4 a cross section on the line 4t-fl, Fig. 2, and Fig'. 5 a cross section on the line 5 5, Fig. 2.

Similar letters refer to similar parts in the several views. i

Referring to the drawing, p is the guide rod inserted in the handle t and having the usual presser toot, at its lower end. On the rod 77 slides a guide shoe 17, in which the needle-support .J isrotatably mounted on the pivot y. The needle o is secured in the needlc-siu'ijjiort by means ot a screw u. The guideshoe y, together with the needle a, are moved up and downby means of a reciprocating rod f. Said rod carries a foot e which bears either against a guard formed ot lugs el, d on the upper end of the guide shoe y when the guide shoe is being pulled up or against the lateral walls n, n of the guide-shoe g when the guide shoe is being .toit-ed down. The length of the stroke of the needle a is limited in the downward direction bv a stop m striking against the handleA t. .lhe position of the stop m on the rod f can be adjusted. The stop has two lags which are each provided with a holem through which passes the rod f. A spring /l-.r forces the wall ot one or the other hole uz into one ot the notches Z provided on the rod T. '.lhus the length of the stroke of the rod ,t and the needeA a, and therefore also the length. of the loops, may be regulated.

`W ith this arrangement the maximum stroke is notl limited to the distance between the tirst and last notches, but to that distance plus the length of the stop m, because the bow may be moved to a position where the lower hole engages with the upper notch, or it may benioved down so( that the upper hole engages with the lowermost notch` thus providing for a wide range ot adjustment. A greater retinemcnt of adjustment may be attained by so locating the notches that only one hole in the bow will engage with a notch, the other hole engaging with the rod between two notches illustrated. This adjustment may then bc equal to halt the distance between notches.

In using the machine the head 'o on the rod f is held with one hand and the handle t with the other hand, the presser toot being in Contact with the fabric at. all times. By moving the head o up and down, the needle a is passed through the fabric and is drawn back. The. rod f is provided with an eye o, through which passes the emhroidcringthread 1' 'coming from a suitable source of supply such as the usual coil and passing through the eye of the needle. Then the eye of the needle passes through and below the fabric and draws the loop of thread 7" with it, the thread is ii'ree to pass through the eyeo. When the head o is moved upward the thread r becomes pinched between the lugs (Z, d and the foot c of the ascending rod f, thus forming the loops. By' this arrangement the length of thread between the eye o and the eye ot the needle is unchanged, so that the delivered length ot' thread is always the same for ,the formation of the loops; these latter are therefore of uniform length.

In hand embroidering machines, ash'therto known, the length ot' the stitches depends on the stroke of thc connecting rod. because the oscillations of the needle'support e are limited by a iixed lug. 'lherct'orc the' stitches are long or short as the loops are made long or short by the adjustmenty of the machine. For the purpose of producing diiiercnt lengths of stitches irrespective of the'lengths of the loops the needle-support is provided according to the present invention with an adjustable lug. The latter consists of a screw t) screwed in the needle-support z and maintained in the desired position by means of a nut c. By screwing iu the screw b to the full extent the needle o will be adjusted so as to assume a vertical posi-tion, so that the needle makes the holes in a single place only in the Jfabric and any numberot loops may bc formed at the said place. As the screw L is screwed outwardly the needle a With the needle-support will be also tilted, and the length"of the stitches will be increased. The extent of inclination or the needle support Will determine the length of the stitches.- Theneedle-support is.

combined with a 'spring w, engaging with the end of the needle-guard below its pivot y, and tending to engage the support with the screw. rI'his spring Will be compressed as the needle is pushed into the fabric, thus allowing the needle to assume the-vertical position at the end of its down stroke; at`

hand embroidering machines have been made With vertically reciprocating ,needles forming loops below the cloth, I therefore do -not claim such a machine broadly; but

I claim: i

A hand embroidering machine having a needle support, a needle, an operating handle, a reciprocating rod sliding in the handie, and means for determining the extent of movement of the needle, such means corn'- prising an adjustable stop, said stop having two legs, a perforation in each leg through which the rod passes, said-rod havin a series of notches, there being a spring or engaging a leg of the `stop with a notch on the rod.

In testimony whereof I have 'signed my name to this specification in the presence of two subscribing Witnesses. i WENZEL ANTON RADOUS.` lvitnesses:
